Specifying the Active ITS Service 
Before publishing an Internet Transaction Server (ITS) service, you must specify the currently active service, because the Build and Go functions in the SAP@Web Studio publish toolbar always operate on the currently active service:
Procedure
To specify the currently active service:
The SAP@Web Studio displays a sub-menu of services in the current project.
The SAP@Web Studio highlights the selected service in the project workspace File View.
Result
The SAP@Web Studio applies all subsequent Build and Go operations to the currently active service.
